Abstract (en)
[origin: EP1138958A2] A fluid-operated circuit for setting the top dead center (TDC) and the bottom dead center (BDC) of the punch actuation cylinder (1) in punching machines comprises a first copying distributor (5) which distributes pressurized fluid, which has a spool (5a) at one end and can be connected in output to the upper section (2a) of the chamber (2) in which the actuation cylinder (1) slides and in input to a first pump (8) for feeding low-pressure fluid and to at least one first fast-acting electric valve element (6); the spool (5a) can be pushed into position by contact by a corresponding setting element (4) with continuous micrometric movement. <IMAGE>
